RECEPTACLE FOR HOLDING GASES UNDER PRESSURE.

SPECIFICATION forming part of Letters Patent No. 244,245, dated July 12,1881.

Application filed February 21, 1881.

To all whom it may concern:

Be it known that I, WALTER M. JACKSON,

of Providence, in the county of Providence,

and in the State of Rhode Island, have invented certain new and usefulImprovements in Receptacles for Holding Gases Under Gompression; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, reference being bad to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

This invention relates to certain improvements in receivers or holdersin which gas or gases of any description can be condensed and storedunder great pressure.

Heretofore all receivers or holders for this purpose have beenconstructed of metal, such as brass, steel, or iron 5 but they haveproved defective and impracticable for the purpose, owing to theporosity of the metal, which permits the gas to gradually escape throughthe walls of the receiver.

The object of my present invention is to obviate these defects andprovide a receiver or holder that will be almost, if not wholly andabsolutely, impervious to gas, and in which a large amount of gas can becondensed and imprisoned and drawn off as required for use.

To this end my invention consists of a receiver or holder constructedmainly of paper, and saturated with a suitable composition or substanceto render it impervious to gases, as more fully hereinafter specified,

I accomplish the above-mentioned objects by the apparatus illustrated inthe accompanyin g drawings, in which- Figure 1 illustrates a perspectiveview of my improved receiver or holder; Fig. 2, a detached view of themain portion of the receiver and its heads, and Fig. 3 a detached viewof one of the bolts and screw-nuts by means of which the heads arebolted to the body. L

The letter A indicates the main portion or body of the receiver orholder, which is constructed, preferably, of one continuous piece. Thisis wrapped around a rotating arbor or (No model.)

mandrel, and during the wrapping is saturated continuously, in anyconvenient manner, with a suitable compound or substance which will fillthe pores of the paper, strengthen it, and renderit impervious to gas. Ihave found in practice that a mixture of gelatine and glycerine, inabout the proportions of one part of gelatine to twenty parts ofglycerine, forms a compound well adapted to this purposefor generaluses; but I do not limit myself to such proportions, as they may bevaried considerably without departing from this part of my invention.

The arbor or mandrel is preferably disjointed or disconnected betweenits ends, so that after the body of the receiver or holder is made itcan be readily removed.

The letter B indicates a flange, one at each end of the body of thereceiver or holder. These are preferably turned up during the process ofrolling, but they may be formed in any other convenient manner. To theseflanges are fitted the heads 0 l). The heads 0 are struck up inconcavo-convex form out of paper, and the heads D of similarly-shapedsteel disks, and the whole are bolted securely to the flanges by meansof the longitudinal screwbolts E, provided with the screw-nuts F.

The joints between theheads and the flanges of the receiver or holdermay be made tight by means of any suitable cement or composition.

The letter G indicates a pipe through which the compressed gas may bedrawn off for use. This is provided with a check or regulating valve, H,by means of which the gas may be delivered from the receiver or holderat a uniform pressure, no matter what the pressure may be in thereceiver.

The receiver and holder as thus constructed I have found by practicewill contain practically one thousand cubic feet of gas to one cubicfoot of capacity, which can be delivered, by use of the check orregulating valve, at a uniform pressure of three inches of water orthereabout, so long as the pressure in the receiver or holder exceedsthree inches of waterpressure.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A receptacle or holder for compressed gas 5 or gases, constructed ofpaper combined with gelatine and glycerine, substantially as specified.

2. The combination, with the body of the receptacle or holderand thepaper heads thereof, the steel heads and bolts for securing the 10 sametogether, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of February, 1881.

WALTER MARSH. JACKSON.
